Hydrothermal energy:
The carbon-free, baseload energy solution for Australia.
Northstar Energy is powering the earth with the power of the earth. We will serve Australia’s future energy needs with baseload, carbon-free, renewable, non-weather dependent, scalable, lower cost, low risk, safe hydrothermal energy.
We are planning and developing carbon-free, baseload power stations across Australia’s best hydrothermal fairways.
We use shallow hot water not deep hot rocks.
Northstar’s uses a heat exchange process to transfer heat from subterranean hot water to a working fluid (with a lower boiling point than water) which is then used to generate electricity.
- Uses hot water down from 1,600m at temperatures between 80°C and 160°C.
- Repurposing suspended gas wells to access the thermal heat source to save drilling costs.
- Working fluid has a low boiling point than water.
- Downhole, a patented heat exchanger transforms the hydrothermal energy boiling the working fluid into vapour
- The process is a closed loop system and the Organic Rankine Cycle uses the pressurised vapour produced to spin the turbine of the generator
Northstar has secured vast geothermal acreage in Queensland, South Australia, New South Wales and Tasmania.
We have a fast growth pathway to 1,000MW.
We will help serve Australia’s renewable energy target of 75% by 2035.
The power of the earth.
Nature’s infinite
energy
We harness the earth’s natural heat to generate clean, renewable electricity. By tapping into hydrothermal energy, we unlock a limitless power source that exists beneath our feet - steady, reliable and sustainable.
Always on, always reliable
Unlike solar or wind, hydrothermal power isn’t dependent on the weather. It provides continuous, baseload energy that keeps communities and industries powered day and night - no interruptions, no compromises.
Safe, scalable and sustainable
Our hydrothermal systems are designed for longevity, safety and scalability. With a proven and low-risk heat exchange process, we can expand energy generation to meet Australia’s growing demand with minimal environmental impact.
Powering Australia’s future
With vast geothermal acreage in Queensland, South Australia, New South Wales and Tasmania, Northstar Energy is leading the transition toward a carbon-free energy future.
